Mosdos Yesod Olam is the banner under which R’ Moshe Wenger set up three wonderful kollelim located in Beit Shemesh and Yerushalayim six years ago. His vision was to enable the growth and unhindered learning of true bnei torah in Eretz Yisroel.

Kollel Har-Tzvi is a vibrant kollel for young avreichim in Yerushalayim. Led by Rav Yaacov Ellituv, the avreichim come together to learn b’iyun for two sedorim a day – not just as a group learning the same sugya, but as a true chabura. Together, they deepen their understanding in the sevaros of the Rishonim. A journey into the batei medrash of Rashi, the Ramban, the Rashba and more.

“Ellituv’s,” as it is fondly known, is a place of true achdus, a place where avreichim, inspired by the Rosh Kollel, are truly there for each other b’ruchniyus u’b’gashmiyus – a unit, a team. As a kollel that strives for greatness, we don’t “just” learn, we shteig.

Kollel Shoneh Halachos, led by Rav Shimon Sofer, is a vibrant community of committed avreichim in Beit Shemesh, focused on mastering halachah with practical applications. Currently engaged in the study of Hilchos Niddah, this kollel combines rigorous learning with the ability to apply it to real-life situations. Our dedicated avreichim exemplify true hasmadah and ameilus baTorah. We don’t “just” learn it, we live it.

Step into Kollel Toras Moshe in Beit Shemesh, and you’ll hear the beautiful kol Torah, the rustling of dapei Gemara, and the joyful discussion. Led by Rav Yair Kruskal, the avreichim are delving into Meseches Avodah Zorah, daf after daf. Their incredible persistence and devotion allows them to complete multiple masechtos in depth each year, an incredible achievement that shows the hasmadah of the kollel. We don’t “just” learn it, we’re koneh it.

At Mosdos Yesod Olam, Torah doesn’t just enrich the mind, it enriches the person as a whole. Because when you live and breathe Torah like our avreichim, Torah becomes your essence. It changes the way you live.
